Abstract

The feeding value of mixtures of Panicum maximum and Centrosema pascorum were
investigated with Red Sokoto bucks, by feeding with Panicum: Centro hay at different
mixtures of 80:20, 70:30, 60:40 and 50:50, respectively. Four mature bucks with average
body weight of 13.12kg were used in a 4 X 4 Latin square design, during which feed intake,
digestibility and nitrogen utilization were monitored. Significant (P<0.05) difference in the
basal diet intake was observed, with animals fed 50:50 diet having the higher value
(166.88g/day). There was no significant difference (P>0.05) in the daily feed intake of
animalfed 70:30 and 80:20 mixture diets. Similar trend was also observed in total feed intake
and dry matter intake. Animal fed 50:50 diet had significant highest (P<0.05) crude protein
(CP) digestibility (61.85%) while those fed 80:20 diet recorded the least (54.39%). The crude
fibre (CF) digestibility increased significantly (P<0.05) from 57.67% in 80:20 diet to 65.72%
in 50:50 diet. Nitrogen intake was significantly (P<0.05) affected by dietary treatment, with
:80:20 diet having theleast N intake (7.12 g/day).which increased with increase in the level
of Centro with animals fed 50:50 diet having the highest value (9.76 g/day). Both nitrogen
absorbed and nitrogen retained as percent of intake for 50:50 diet were significantly (P<0.05)
higher as compared to all other treatments, with 80:20 diet recording the least values. It can
be concluded that feeding 50:50 and 60:40 P. maximum to Centrosema pascorum mixture
produced the best result in terms of nutrient intake, digestibility and nitrogen balance in Red Sokoto bucks.
